System.Drawing.Common is deprecated on non-Windows platforms

See original GitHub issue

Hello, I work on the .NET Libraries team, and I saw that this library has a lot of usage in the community and depends on System.Drawing.Common for xplat scenarios.

We just made the decision to make System.Drawing.Common a windows only library starting .NET6+ due to a lot of reasons after a long discussion. You can see more details here: https://github.com/dotnet/designs/blob/a15a8c7a324c482c5e38b73e46c2afe56f6bd504/accepted/2021/system-drawing-win-only/system-drawing-win-only.md

Also: https://github.com/dotnet/docs/issues/25257

We wanted to reach out so that you could react to this changes when .NET 6 is released. Also if you have any questions/concerns please do let us know at https://github.com/dotnet/runtime

What is the recommended action to still support winforms/wpf scenarios for example as I see your library does?

You can mark those APIs as windows only using the SupportedOSPlatform("windows") annotation, and then add new APIs that use another library like ImageSharp or SkiaSharp.

Hi Alex, I will try to port it to ImageSharp, but it may take some time.

Another benefit of removing this dependency would be that the library could also be used with Blazor WASM. I just tried to get a simple Wifi QR Code Generator working, but unfortunately this is not possible, since System.Drawing is not supported in Blazor WASM.
